Showing first {{hits.length}} results of {{hits_total}} for {{searchQueryText}}{{hits.length}} results for {{searchQueryText}}

Whenever I'm writing long LaTeX documents I always find myself jumping backwards and forwards in the code trying to remember what I named a \label. To save me losing my place in the code I use the showlabels package which displays the name of the label next to the corresponding equation. Then I can look in the PDF where it's easier the find the equation I'm looking for and I don't need to jump around in my code. It works on nearly everything you can assign a \label to. Marvellous!


In your preamble put:


Example output



You can provide an option to showlabels to tell it where to place the labels:


Available options are (taken from the documentation):

  • outer [default]—all notes are placed in the text's outer margin
  • inner—inner margin
  • left—left margin
  • right—right margin
  • marginal [default]—put notes in the margin
  • inline—put notes inline, as much as possible, and ignore any of the margin-placement options above
  • nolabel—do not insert a marginal note for \label commands
  • draft [default]—does nothing, partner of...
  • final—turns off all the package's functionality

Note that showlabels should be included after the packages amsmath and hyperref to work correctly with them. See the official documentation (PDF) for more details.
